Ali Hajimiri Scientist

Ali Hajimiri is an academic, inventor, and entrepreneur in various fields of technology including electrical engineering and biomedical engineering. He currently holds the Thomas G. Myers Professorship Chair of Electrical Engineering and is also a Professor of Medical Engineering at the California Institute of Technology (Caltech).He received the B.S. degree in electrical engineering from Sharif University of Technology and his M.S. and Ph.D. degrees in electrical engineering from Stanford University. He has also worked for Bell Laboratories, Philips Semiconductors, and Sun Microsystems. As a part of his Ph.D. thesis he developed the time-varying phase noise model for electrical oscillators, that is also known as Hajimiri phase noise model. In 2002, he cofounded Axiom Microdevices Inc. together with former students, Ichiro Aoki and Scott Kee, based on their invention of the Distributed active transformer (DAT), which made it possible to integrate RF CMOS power amplifier suitable for cellular phones in CMOS technology. Axiom shipped millions of units before it was acquired by Skyworks Solutions in 2009.He and his students demonstrated the world's first radar-on-a-chip in silicon technology in 2004.He and his team are also responsible for development of an all-silicon THz imager system where an integrated CMOS microchip was used in conjunction with a second silicon microchip to form an active THz imaging system, able to see through objects with various applications in security, communications, medical diagnostics, and human-machine interface.In 2013, he and some of his team members demonstrated a complete self-healing power amplifier, which could recover from various kinds of degradation and damage, including aging, local failure, and intentional laser blasts by using an integrated self-healing strategy.He was selected to the world top 35 innovators under 35 (TR35) at the age 32.He is an IEEE Fellow and has been the recipient of numerous other awards. He was recognized as one of the top 10 authors in the 60-year history of ISSCC in 2013. He hold 70 granted U.S. Patents.
